In the United States, the water flow rate is measured in gallons per minute (GPM). Plumbers using the metric system will measure the water flow rate in liters per second (l\/s).<\/p>\n\n\n\n\n\n<h2>Types of flow rates<\/h2>\n\n\n\n<p>There are 2 main types of flow rates:<\/p>\n\n\n\n<ol><li>service flow rate &#8211; the regular flow rate in your home.<\/li><li>peak flow rate &#8211; When flow rate is maximized via all plumbing appliance being on maximum.<\/li><\/ol>\n\n\n\n<p>Both of these flow rates are important to know so that you can ensure your faucets, toilets, and showers are able to function properly in any situation.<\/p>\n\n\n\n<h2>How do you calculate the water flow rate?<\/h2>\n\n\n\n<p>The equation for the flow rate is as follows:<\/p>\n\n\n\n<p>Flow rate = Velocity * Volume of Water<\/p>\n\n\n\n<p>You can calculate your plumbing appliance&#8217;s flow rate by using the following steps:<\/p>\n\n\n\n<ol><li>Set a timer for 6 seconds. Turn on the cold water up to max to ensure maximum water flow. You&#8217;ll want to catch the flowing water in a measuring cup or bucket.<\/li><li>As soon as you start the timer, begin collecting the water in the bucket. Once the 6 seconds is up, stop the water.<\/li><li>Use the meauring cup to determine how much water you were able to collect, and convert it into gallons (There are 16 cups in a gallon).<\/li><li>Multiply the number you get by 10 and that will be the flow rate in GPM.<\/li><\/ol>\n\n\n\n<h2>What affects water flow rate?<\/h2>\n\n\n\n<p>Your home&#8217;s water flow rate can be affected by a number of factors. These factors include:<\/p>\n\n\n\n<ul><li>Temperature<\/li><li>Length and diameter of the pipes<\/li><li>The number of bends, rises, and falls in your pipes<\/li><li>The number of valves and fittings in your pipe layout<\/li><li>The conditions of the entrances and exits of the pipes (ex: clogged pipes)<\/li><\/ul>\n\n\n\n<h2>What hot water flow rate do i need?<\/h2>\n\n\n\n<p>If you are looking to purchase a <a href=\"https:\/\/www.pvcworkshop.com\/best-tankless-water-heaters\/\">tankless water heater<\/a> or other heating appliance, you&#8217;ll want to be able to calculate the correct GPM you&#8217;ll need for your home. Below is a rough estimate of what the hot water flow rate should be:<\/p>\n\n\n\n<ul><li>1-2 people\u201423 to 36 gallons<\/li><li>2-4 people\u201436 to 46 gallons<\/li><li>3-5 people\u201446 to 56 gallons<\/li><li>5 or more people\u2014over 56 gallons (add 10 gallons per additional person)<\/li><\/ul>\n\n\n\n<h2 class=\"gb-headline gb-headline-ce1f3406 gb-headline-text\">What is the water flow rate for a shower?<\/h2>\n\n\n\n<p>A shower&#8217;s water flow rate will be about 2-2.5 GPM. Showerheads that have a <a href=\"https:\/\/www.epa.gov\/watersense\/watersense-label\">WaterSense label<\/a> will not be any higher than 2 GPM as they are required to meet EPA&#8217;s specifications for water efficiency.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Water flow rate is the amount of water that flows through a pipe or tube over a certain period of time.
